Product Details

The Dayco Small I.D. Heater Hose line is engineered for HVAC coolant routing where compact hose sizing is required. Part number 87819 uses EPDM rubber, a material commonly selected for coolant and heater hose applications because it handles heat and fluid exposure in engine bay environments. This hose is specified with a 5/8 in. inside diameter on both ends and a single I.D. hose layout, making it suitable for heater outlet connections on the listed Toyota vehicles. Dayco 87819 also includes a protective sleeve and measures 19 1/2 in. in trunk height.

Compatible With 2007-2009 Toyota Camry, Heater Outlet; 2004-2008 Toyota Solara, Heater Outlet; and 2002-2006 Toyota Camry, Heater Outlet. This part cross-references Toyota 87245-06170 and 87245-06470 for the same application.

Common Issues This Hose Can Address

• Cracked or hardened heater hose material
• Coolant seepage at the heater outlet connection
• Restricted heater coolant flow from a deteriorated hose
• Heat-related hose wear in the engine compartment
• Replacement needs for a 5/8 in. small I.D. heater hose

Installation Notes and Tips

Verify the hose routing, end diameter, and heater outlet position before installation. Confirm the vehicle is not a Japan-built 2007-2009 Toyota Camry, since that application is excluded. Inspect adjoining heater pipes and clamps for wear, and replace any damaged sealing surfaces before installing the new hose.

Dayco manufactures this heater hose to meet SAE J20R3 Class D-1 and SAE J1684 Type EC specifications, supporting consistent material and performance requirements for HVAC hose service.
